How to get NSAlert to properly display the App Icon on Big Sur in the AutoFill Credential Provider extension?

When displaying an NSAlert in the AutoFill Credential Provider extension context on macOS 11 Big Sur, the App Icon is not properly displayed. Instead, a Ghostbusters-esque cross-out graphic is displayed over the icon. This is currently present in Xcode 12 beta 6 on macOS Big Sur beta 6.

Does anybody know how to fix this?

I've filed a bug report: FB8689228.

To reproduce: add an AutoFill Credential Provider extension to your Mac App project. On viewDidAppear, attempt to display an NSAlert.


Good news! This appears to be fixed as of Big Sur Beta 7.
